Electric Oil Pump OPM OPM-115, OPM-220
Congratulations on purchase of this World Class Electric Oil Pump!
This is an AC Gear Oil Pump designed for use with AC Power. Pump uses 2 Sintered Powder Metal gears for suction & is designed for use with oils up to SAE 90 in addition to be used with Waste Oil & a variety of other media. In ideal condition, pump dispenses up to 4.4 GPM (16.6 Litres) at the pump outlet. The actual discharge varies depending on media being used, temperature, Hose Length etc. Pump Comes in 2 Power Ratings 1. 115V AC, 60 Hz 2. 220V AC, 50/ 60 Hz Rating is marked on the pump motor Since every country has different power sockets, it may so happen that the standard power socket provided with the pump may not fit directly into your power source. Use an adapter to convert the pin style on the pump to match with your power socket. In case you need to extend the power cord, use a power cord extender with female socket that would fit into the power cord fitted onto the pump & the male end for the power source

ASSEMBLY & INSTALLATION (DRUM MOUNTING) 1. Wrap around PTFE tape on the following male threaded joints. This will ensure a leak-proof connection • • • •
4. In case the Bung Nut does not fit onto your drum, use a Drum Bung Converter. Note that bung supplied with the pump has 2” Pipe threads
Male Threads on the Elbow Male Threads on the Fitting ends of the Hose Male threads between the 2 Suction Tube parts Male threads on the Suction tube end that fits into the pump inlet
2. Now Fasten the Elbow into the pump outlet & hand tighten. Once you can no longer hand tighten, take a wrench & tighten the elbow by about ½ a turn. Open end of the Elbow should be facing away (not in the direction of the pump motor) 3. Take the Bung Nut & fasten it onto the 2” opening on the Drum. Bung Nut has a large 2” thread & a small 1-1/2” thread. 2” thread goes into the drum, whereas the 1-1/2” thread is for connecting bung to the pump
5. Connect the two halves of the Suction Tube. Suction tube is designed for use with tanks / drums which are 36” (914 mm) deep & has a total connected length of 34” (865 mm).
Elbow facing out
In case you are installing the pump on a tank that is deeper, you would have to get a standard 1” dia. tube with 1” NPT threads on one end. For shallower drums, cut the suction tube to the desired length. Ensure that there is about 2” (50 mm) gap between the bottom of the tank / drum & inlet of the suction tube allowing for easy entry of media into the tube
2” thread goes into the drum
6. Now connect the Suction Tube to the pump inlet. Hand tighten

8. Lift the Pump from the Handle. Be careful as the motor is heavy. Insert suction tube into the drum through the 2” opening on the drum. Use the Swivel Nut mounted at the pump inlet to fasten onto the Bung Nut. Hand tighten
11. End of the Hose has a Ball Valve connected to it. This is just a Non Drip Valve & not a control valve. Ball Valve is further connected to a steel spout. Spout is designed to enter the ¾” opening on the drum which acts as a nozzle holder
9. Take about 30 ml of Oil being dispensed & pour it into the pump outlet through the elbow. This will ensure that the gear chamber stays lubricated & makes it easier for the pump to prime
12. With the Toggle Switch on the Motor in the upward position (switched off), connect the power cord to the AC Outlet
10. Take the Hose Assembly & connect the threaded end onto the Elbow at the pump outlet. Hose has a hex nut at the threaded end which can be tightened to the elbow using a wrench

13. The pump is now ready for use
PUMP INSTALLATION (IN-LINE) This pump can additionally be mounted on a wall for In-Line operation. This is particularly done in a shop environment where the pump may be used with Waste Oil. Note that for Waste Oil Application, pump already has a Strainer installed at the bottom of the suction tube. Pump can be installed using a Mounting Bracket (not provided, but can be ordered separately). This bracket is a simple right angle bracket with two mounting holes that use the motor mounting holes on one side of the motor to attach the pump to the bracket. The bolts used to mount the pump to the motor are removed and then reinstalled through the two holes in the mounting bracket. The other leg of the bracket has 4 mounting holes to mount the bracket to a wall or post. The pump is mounted such that the suction port is down and the outlet port is pointing up. The plumbing back to the storage tank normally goes up from the pump to an overhead pipe to route the plumbing back to the storage tank. A Suction Hose / Tube is installed at the inlet with a strainer where the waste oil enters the hose/tube. 3

PUMP OPERATION 8. Motor is Air Cooled & Thermally Protected which means that the pump can be run for a very long time. If due to any reason, the motor gets heated, it will stop automatically 9. The pump however must never be run dry (no media in the drum) as that can possibly cause irreparable damage to the motor 10. In case ball valve is used to control flow & is closed with the motor on, there will be no media flowing out of the discharge spout; instead media will go back into the pump. Pump has a built-in Bypass valve that will get activated & bypass the media. The ball valve however must never be kept close for more than 5 minutes with the motor switched on 11. Once Dispensing is completed, switch off the toggle switch & disconnect the power cord from the AC outlet 12. Store the Discharge Spout into the ¾” hole on the drum
1. Switch On Power from the AC Outlet 2. Make sure that the Ball Valve is in open position (valve parallel to the hose) 3. Dispensing Spout should be facing the container into which media is to be dispensed 4. Now Switch On the Motor by Pressing the Toggle Switch Down 5. In less than a minute, the pump will be primed & media will start dispensing from the Steel Outlet Spout 6. Dispensing Action can be stopped by Switching off the Toggle Switch on the Motor. It is suggested not to close Ball Valve to Stop flow. 7. Max. 20 Starts / Hour: Time gap between Motor Stop & Restart must be min. 3 minutes. Ball Valve is not designed to be used to control flow, but used primarily as a non drip which is closed after motor is shut down
